Santa's Internet Rules for Children Rosey the Safety Elf, wants all children to know and remember Santa's Rules for using the Internet. 1. Always ask a parent or guardian before you type anything on the internet!  This is the most important rule of all. 2. Never type your last name.  Santa knows who you are! 3. Never give out your address or your phone number.  Santa knows where you live, how else would he find your house on Christmas Eve?!?
